A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human there are 31 pairs of spinal nerves, one on each side of the vertebral column. These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. There are eight pairs of cervical nerves, twelve pairs of thoracic nerves, five pairs of lumbar nerves, five pairs of sacral nerves, and one pair of coccygeal nerves. The spinal nerves are part of the peripheral nervous system.
Two important sacral nerves to the functioning of the bladder and bowel are the pudendal nerve and the pelvic splanchnic nerve. Through a series of reflexes and signals the nerves and the bladder and bowel coordinate with the pelvic floor muscles and external urinary and anal sphincters. This coordination ensures that the sphincters remain closed, opening only during micturition (a term for urination) or defecation.
